BAND I JamesjH :Reichart, Muncie, Ind. Application NoVernberlS, 1943;Serial No..51l),258 T l This invention relates to a contractible bandstructure.

Oriepbject of this invention is to providea contractible bandstructurethatis of comparatively' w simple character. i

other object of this invention is-to incorporate therein a handle socketsuch that a handle maysb'e-retained thereinsimultaneous with band 1contraction. i IA. .further object of this invention is to incorporatein a handleso'cket include-d collapsible band, means for simultaneouslyclampingthel handle in the socket by tautening the band for.

The adjacent ends l6 of the band. are curled, but maybe otherwiseenlarged. Such enlarged ends are slightly offset so as to position sameslightly outwardly from the vessel groove, see Figs. 1 and 2, therebymaintaining, when the band is tautened, a guy wire effect therein forhandle socket sustainment.

The handle socket herein includes two handle clamping side plates H,which have upper and .lowerfla'nges l8 and I9, respectively. The outerends thereof are extended towar ds each other as earsilfl and 2|,respectively; and pivots 22 and anchorage or' conversely. simultaneouslytautenin g the bandby causing the socket to clampingly engage: andretain the handle.

J'Stillafuifther object of. the invention is; w. provides. bandtautening structure including two outwardlygdirected open rectangularloops arranged upon collapse :toward the band to. con- .tract the sameandjwhen socket included, to simultaneously clamp the handle inthesocket.

'Ihenchiefi. feature of the present invention resides in theconstruction of the fband,,its connections, etc;, and the handle socketwhereby the severalobjects aforesaidare accomplished.

'Other objects and features of; the invention will ;be setforth-moreiuHy hereinafter.

The full nature ofthe invention will be understood from theaccompanyingdrawing and the following description and claim:lathe-drawing i 1-:isqatop plan viewof a handle; socketend.

In Figs. '3 and 4, there is illustrated a modifiecl form of theaforesaid invention. In one sense it is the converse of that previouslydescribed in that therein socket clamping resulted in band tautening,while in the present form band 1 'tautening. results in socket clampingof the handle.

' Reference is here made to the copendiiig appli I cation Serial No.498,220 filed August 11, 1943, entitled Glass vessel band and handlestructures. Figs. 1 to 4 of the same illustrate the construction andoperation of an open rectangular loop connection included in the endlessband for extending and collapsing same; I

A-minor difference is that handle I'Mis ofa pistol grip type, although it may be as shown'in Fi-gs l and 2.

In thepresent form of the invention side plates I I! are not apertured(see apertures 30 in plates .I'I),but are embossed as indicated at -I28for seating inanohor portion I recesses I21. Here-'- in the band II3includes offset portions H6 eorraforementioned application of which thisapplication also is a continuation-in-part.

Herein the two side plates 2" with upper and lower flanges 2I8 and 2I9,respectively, are provided with ears 220 and HI, respectively, which arepivotally connected by pivots 222 and 223.

Inwardpressure on portion 3 I 6a then will cause one buckle to collapse uponthe band. Continued pressure on portion 3|6a will cause the other buckleto similarly, collapse.

buckles, see Fig. 7.

, The buckles each pass over center, as it were,

The buckles now lap band 313 adjacent eyes 3H5 and the portion 3l6a nowlaps both when so positioned and lockingly hold the entire band unit inthe contracted formation. Naturally, the length of both buckles must beless than the effective length of portion 3| 6a. Band peripheryreduction is equal to the sum of the lengths of both buckles and portion3l6a. This is an ingenious simple contractible structure quicklycontracted or extended eliminating all threaded or the like members.Doublebuckles, if embodied in the Fig. 3 modification, naturally wouldprovide greater band extension whenever desired or required for wide topvessels. Finger pieces like portion I42, Fig. 2, maybe applied to eachend of portion H611 to facilitate band extension.

While the invention has been illustrated and described in great detailin the drawing and foregoing description, the same is to be consideredas illustrative and not restricted in character.

. The several modifications describedherein as wellas others which willreadily suggest themselves to persons skilled in this art, all are considered to be within the broad scope of the invention, reference beinghad to the appended claim.

The invention claimed is:

In a handle and vessel structure including a split band enveloping thevessel for clampingly mounting thereon the combination of a pair ofmembers directed outwardly from the vessel and pivotally connectedtogether at their outer ends for forming a handle receiving andenveloping throat through which the handle projects in oppositedirections, said members having handle clamping socket forming sidesbetween the throat and band, said sides adjacent the vessel end thereofbeing slotted and the band passing therethrough, and band drawing meanscomprising a pair of rectangular loops one at each side of the socket,each loop having its socket adjacent and ,pivotally connected to theadjacent side at the vessel end thereof, the other end of the looplapping and being connected to one end of the band, the band portionsadjacent the side ends crossing each other, one of them being slotted topass the otherfor drawstring operation upon movement of the loops towardthe vessel into band lapping position for band tautening and handleclamping purposes.
